Ciba wasn't the first chromolytic paper made, but coming up with any home-brew dye-destruction color paper would be quite an accomplishment. It probably rates up there right alongside tranny film in terms of needing industrial muscle to produce.

I realize that PE sets pretty high standards here but according to him, homebrew Cibachrome would be just about the only type of color paper that amateurs could possibly make for themselves. While it's trivial to home brew RA4 chems, the paper is out of our reach once it's discontinued.
